A would be the most accurate choice. This is because the shading is above the parabola indicating it’s solutions are greater. And it’s not a positive parabola

Step 
<u>Find the factors of each number</u>
we know that

Step 
<u>Find the greatest common factor (GCF)</u>
the GCF is equal to----------> 
therefore
<u>the answer is</u>
The GCF is 
Y is the easiest to fix because it has no coefficient, and is therefore the easiest to set on the other side of the equation by itself
